POTATO-FEELING MACHINE.

To all whom it may concern:

Be it known that I, ALBERT Bnrnn, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Potato-Peeling Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to potato peeling machines and has for its object to provide a machine for this purpose of extreme simplicity and one which is highly etlicient in practical use.

Another object of the invention resides in the provision of a stationary receptacle and a rotatable element angularly disposed within said receptacle and having an abrasive surface whereby the potatoes are thoroughly agitated and the skins removed without undue waste of the potato.

A further object of the invention is to provide a receptacle of spherical form and a concavo-convex rotary agitating and paring element arranged therein and means for carrying off the waste material.

lVith these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed and illustrated in the accompanyi'ng drawings, in which Figure l is a side elevation of my improved potato paring machine, the hopper or receptacle being shown partly in section; Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1; Fig. 3 is a section taken on the line 33 of Fig. 1; and Fig. 4. is a section taken on the line lr of Fig. 1.

Referring more particularly to the drawing 5 designates a base which in the present instance is of circular form and has integrally formed therewith and rising from its center a standard 6. The lower portion of the standard 6 is tubular in form for the sake of lightness and to reduce the expense in construction. Upon the upper end of tl e standard 6 the hopper or receptacle 7 is ar ranged. This receptacle is semispherical in form and is provided with a tubular extension 8 which is adapted to oe received in a socket 9 provided in the upper solid end portion of the standard 6. A set screw 10 is Specification of Letters Patent.

threaded through the standard and has binding engagement with the extension 8 whereby the hopper or receptacle is rigidly secured in the standard and rotative movement thereof effectually prevented. The receptacle 7 has formed on its periphery an annular angularly disposed flange 11. This flange is formed with spaced cars 12 to receive an car 14: formed on a concavo-convex door plate 14. This plate when the door is closed lies in the same plane as the wall of the receptacle 7. A suitable pivot 15 extends through the cars 12 and l t, said door being provided at its opposite side with a suitable catch whereby it may be held in its closed position. The vessel 7 is further provided with a cover 16 which is also semispherical in form and is hingedly mounted upon the upper edge of said receptacle. A spray pipe 17 extends through the top of the cover 16 and is adapted to be connected to a iitable source of water supply.

Upon the standard 6 a laterally extending arm 18 is formed and a beveled gear 19 is rotatably mounted on the outer end of said arm, said gear being rotated by means of a suitable crank 20, though it will be understood that the device may also be operated by an electric motor or other means as will be obvious from an inspection of the The receptacle 7 is formed with a second radially extending sleeve 21 and through this sleeve a shaft 22 extends. A short pipe 22 extends through the wall of the receptacle adjacent to said shaft and through this pipe lubricating oil is adapted to be fed to the shaft. A beveled pinion 28 is fixed upon the lower end of this shaft and meshes with the gear 19. The inner wall of the vessel or receptacle 7 is formed with a boss 24 through which the shaft 22 extends and upon the upper end of this shaft the concave-convex agitating and paring element 25 is secured. The element 25 and the gear 23 may be secured to the shaft by means of suitable set screws so that they may be readily removed when it is desired to dismantle the machine. From reference to Fig. 1 it will be seen that the concavoconvex element is angularly disposed with relation to the horizontal axis of the receptacle. The inner or concave surface of the plate 25 is covered with carborundum or other suitable abrasive material whereby sufficient friction is provided to remove the skin from the potatoes as they contact therewith in the rotary movement of said plate. Owing to the angular disposition of the paring element the potatoes will also be thoroughly agitated in the operation of the machine so that they will not remain for any length of time stationary upon the rotating plate, thus obviating the liability of wasting the potato.

A waste pipe 26 is fitted into the upper end of the standard 6 and extends laterally therefrom beneath the sleeve or extension 8 and as the potatoes are pared, the water which is being constantly sprayed into the machine and upon the potatoes through the pipe 17, will wash the skins and other refuse material out of the concave-convex plate and into said waste pipe. It will be observed that there is sutiicient space between the circumscribing edge of the member 25 and the inner wall of the vessel or receptacle 7 for the skins to pass bet-ween the same. Thus the potatoes being pared are at all times kept free of parings.

From the foregoing it is believed that the construction and operation of my improved potato paring machine will be readily understood. It is extremely simple in construction and owing to the few elements employed it is obvious that it may be manufactured at a very low cost. The parts may also be quickly put together or disassembled for cleaning or repairing purposes.

While I have stated that :arborundum is the preferable abrasive material. employed in the operation of the machine, it will be understood that sand paper or any other desired means may be employed in order to effect the desired. result. It will further be understood that while I have specifically shown and described the preferred construc tion and arrangementof the various elements the machine may be modified in many particulars without departing from the essential feature or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is 1. In a machine of the character de scribed, the combination with a receptacle, of a rotary abrading element having a concave abrading surface, the rotative axis of said element being disposed through the wall of said receptacle and at an angle with relation to the vertical and horizontal axes of said receptacle.

2. In a machine of the character described, the combination with a spherical receptacle, of a rotary concavo-convex plate having an abrasive surface arranged within said receptacle, the axis of rotation of said plate being disposed at an angle to the hori zontal axis of the receptacle.

3. In a machine of the character described, the combination with a support and a spherical receptacle rigidly fixed thereon, of a rotary concavo-convex plate having its concave surface covered with abrasive material, said plate being mounted within the receptacle and having its rotative axis disposed at an angle with relation to the horizontal axis of the receptacle, the convex wall of the plate being spaced from the wall of the receptacle, and means for withdrawing the waste material from said receptacle.
